Break the wind.
A wind jacket like the Louis Garneau X-Lite Jacket is one of the most important accessories a cyclist can own. It really only serves one purpose, but that purpose is almost universally useful. During windy rides, you can wear it without overheating. Or, as the temperature falls, you can replicate the wind stopping and insulation of a $300 winter jacket by wearing it over a thermal base layer. And if you ever decide you're overdressed, it's so ridiculously lightweight that it can be stowed in a pocket in the collar, which can then be easily stashed in a jersey pocket.
The X-Lite's construction is simple and effective, using two fabrics from LG's X-Lite family. X-Lite 19 is the business end of the jacket. It's wind resistant, has a high denier for durability, and still manages to breathe well so your wind-free microclimate doesn't turn clammy and damp after thirty minutes in the saddle. X-Lite Mesh is a lightweight mesh designed for one thing: comfort. Well, and stretch. And breathability. OK, so it does lots of things, all of which make it the material you want for optimal ventilation, which is why LG uses panels of it for the X-Lite Jacket's underarms.
The jacket is cut according to LG's pro fit, which means it's snug enough for racing and there's no extra material to flap in the wind that it's designed to block. The articulated elbows and stretch trim at the collar, wrists and hem mean you'll be able to move freely in the saddle — including reaching into jersey pockets through the rear access back opening — without compromising comfort. The full-length zipper has a neck garage to eliminate chafing, a full-length flap, and reflective accents. The chest and upper back have yet more reflective elements to help keep you visible in low-light conditions.
The Louis Garneau X-Lite Jacket is available in six sizes ranging from X-Small to XX-Large in the colors Black/purple, Bright Yellow, Diva Pink, and White/black.
